It never occurred to me to throw a tube in, in an emergency. Duly noted should I get such tyres
What's the length of the spindle? can you not adjust the cups of the bracket so you get the offset?The bottom bracket is an unusual (old) size and the LBS couldn't help. Or more precise, didn't have one in stock. He was dead helpful and let me take what he had home tobtry.
On mine, the length of the spindle sticking out of the bb is 5mm shorter on the drive side, so a standard bb puts my chainset too wide and I'm getting massive chain rub, especially at the extremities. I'm going to have to take Sweeney-like measurements and scour the internet. On the plus side, I found a fiver on the way home from the LBS.🙂
Carbon frame and bonding questions.
My carbon framed CX bike has developed an issue. The aluminium seatpost insert started to rotate. I've got it out of the frame. Frame and insert are undamaged, but it looks like it may have happened before and the previous owner has had a go at gluing it in. The adhesive was poorly distributed and probably not suitable for the job. I'm going to have a go at it myself.
Getting the insert clean shouldn't be a problem. Do I need to coat the surface to prevent galvanic corrosion (?) or will the adhesive suffice?
Cleaning inside the carbon seatpost. I'm thinking of taping a bit of scotch pad to a drill bit and giving it a whizz. Any better ideas?
Wiping down, was going to use acetone. Any issues using it on carbon?
Going to use this stuff.

Any other suggestions?
Any suggestions on wiping away the excess that's likely to gather in the insert and seatpost, as I push it in? I'm thinking mainly about the possibility of a big lip appearing at the bottom of the insert. Small traces can probably be removed with the drill/scotch pad combo when fully set.
Any other advice?
Again, I now understand. Could you fit a second seat post clamp, double clamping each piece with a slot in to secure it. Its a bit of a fudge but would sort it for the sake of a couple of quid and a few ounces?It definitely glues in.
There's a lip on the insert, just below the gold/bronze band. It is wider than the rest of the insert and sits proud of the seat tube. The seatpost clamp attaches to the black bit.
